Anyone know or know where I can get a engine schmatic which shows where the oil galley plugs are on a 371 olds block primarily in the rear. Had a machine shop rebuild motor and now I can't get oil to the driver's side galley in sufficient volumn for the lifters. It seems to be a lack of back pressure which also affects oil thru the #2 & #4 cam lobes to the rocker assemblies. No blockage. Suspect that the oil is being dumped back into the pan rather than upstairs. Oil pump was changed out with a new one and still no change. Don't want to pull motor if possible - any help would be appreciated - papadoc
